Why is my coolant turning orange?
Watch for signs of oil or rust. The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). This is not good; it usually means that a head gasket, intake manifold, or transmission oil cooler is leaking oil or transmission fluid into the engine coolant.
When does the coolant temperature warning light turn on?
The coolant temperature warning light turns on when your engine is sensed to be too hot and is at risk of damage from overheating. Is it safe to drive with the coolant temperature warning light on?
What causes a car engine to overheat when there is no coolant?
Low Coolant By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine’s cooling system relies on coolant to circulate and remove heat from the engine. If you don’t have enough coolant in there to do the job, heat will build up and your engine will overheat.
What kind of coolant do you use on a hot engine?
Engine coolant is often sold as a 50/50 mix of water and coolant. You can also buy concentrated coolant and mix it yourself. Safety tip: Never add coolant to a hot engine. Wait for the engine to cool before removing the cap or pouring in coolant.
What causes coolant to boil on hot engine?
Removing the cap from a hot engine will cause the coolant to start boiling and the steam will most likely burn you. Once the engine has cooled, check the overall fluid level of the coolant. If the level is low, you can add just water temporarily so that you can drive somewhere to get the car checked out.
Why did the coolant in my car’s cooling system turn brown?
Any or all causes of dirty coolant is reason to perform a cooling system flush. After performing the flush, check the coolant regularly to ensure that the problem does not reoccur.
Why are car coolant and antifreeze different colors?
Vehicle fluids vary in colour from bright pink to reddish-brown, so if you ever need help identifying which is which, take a look at our car fluid finder chart. As for coolant/antifreeze, there are a couple of key differences as to why some products are one colour and others are another, as our expert Bruce Ellis explains below:

What causes oil and antifreeze to come out of radiator?
You likely have an internal head gasket leak. The crack in the gasket is allowing oil from the engine cylinder to seep into the coolant chambers and that gets pumped around the engine and back to the radiator. Oil and antifreeze when mixed looks like a milky brown goo.
